Congrats to @abhirupdikshit.bsky.social for this conversation article talking about the findings of our research into flash drought and fire. We found that fires that occur with a combination of standard droughts and flash drought produce more sever fires.

Jason P. Evans @jasonpevans.bsky.social · 30/07/2026
I'm happy to see this work led by @abhirupdikshit.bsky.social published. Analysis of these global datasets show that the occurrence of flash droughts amplifies the severity of fires. This is something fire agencies should account for when planning their fire response strategies. @ccrc.bsky.social
